What is the grade of ASTM A36?

What is the grade of ASTM A36?

ASTM A36 Steel Plate is one of the most common grades of steel used in structural applications. This mild carbon steel grade contains chemical alloys that give it properties such as machinability, ductility, and strength that are ideal for use in constructing a variety of structures.

What material is Q235?

plain carbon structural steel
Q235 is a plain carbon structural steel that is used throughout China. It is also known as Q235A, Q235B, Q235C, and Q235D. Since it is mild steel, it is utilized in production without heat treatment. The Q designates the yield point, and the 235 indicates the yield strength.

What is the ASTM equivalent of q235b?

Q235 steel plate equivalent steel standard-astm a36 . A36 steel plate is similar to Q235B steel plate, it is one Q235b equivalent steel standard, another one is SS400. While the difference between A36 and Q235B is as follows: Different Tensile Strength (A36=400-550MPa, Q235B=375-500MPa); Different element content requirements: (A36: C is equal to or less than 0.25%, Si is less than or equal to 0.4%, P < 0.04%, s is less than or equal to 0.05%; Q235B:C=0.12-0.2%, Si is less than or equal to 0

What is the difference between q235b steel and q235a steel?

According to standard GB/T 700,the distinction of Q235A steel and Q235B material mainly lies in carbon content. The carbon content of Q235A steel plates is 0.14-0.22. Q235A material does not need impact test. While Q235B steel need to do normal temperature impact test, V notch.

What is q235 steel grade?

Although the Q235 steel grade steel plate has lower mechanical properties than A36 and SS400 material, but in actual operation process, as long as the buyers do not have special requirement, often these three kinds of materials can be substituted.

What is the tensile strenghth for q235b?

Q235B Included in 3 standards (China) Elongation: > 22 % Impact energy KV 20° С: > 27 J Thickness: 150 – 200 mm ; Yield Strength: > 185 MPa Tensile Strength: 370 – 500 MPa Elongation: > 21 % Impact energy KV 20° С: > 27 J Cold-bend test Longitudial test pieces Thickness: < 60 mm ; Return Bend: d=a Thickness: 60 – 100 mm ; Return Bend: d=2a
